Data is store momentarily in computers in RAM. Random Access Memory are chips that contain registers that retain their electrical state for as long as its either changed or the power is turn off. Data can also be store permanently in a Hard Drive. HD are nothing more than a magnetic disc that spins around while a writing head magnetises the surface of the disc, creating areas to simbolize ones and zeros; the digital language of computers.
A computer can only produce sound if it contains the right hardware. These come in the forms of sound cards or sound chips. In most cases these devices only convert the sound data from digital to analogue signals - the computer itself reads the binary data and decodes it into a form understandable by humans.
Data Validation is a process that ensures that data entered into the database form, a web form, or a computer program conforms to the correct data type.
A group of computers might form a network, but this is not necessarily the case. There is no commonly used collective noun for computers.
On the basis of working principle computer are classified in to three types Ana log computer, Digital computer, and hybrid computer. Ana log computer measures continuous type of data and uses a physicalquantity like electric current, voltage, temperature, etc. to present and process the data. It represent numbers by a physical quantity; that is, they assign numeric values by physically measuring some actual property, such as the length of an object, an angle created by two lines, or the amount of voltage passing through a point in an electric circuit. The computer which accepts discrete data as per the electric signals is known as digital computer. Basically , digital computers counts digits, which represent numbers or letters. The computers based on binary digits i.e. 0 and 1 are called digitals computer. It represents each and every information in terms of single numbers and processes the information by using standard arithmetic operations. Hybrid computer is the combination of the feature of Ana log and Digital computers.
Computers record data in the form of "bits", Binary Digits.
ANALOGUE COMPUTERS ARE THE COMPUTERS WHICH PROCESS DATA IN A WAVE FORM WHILE HYBRID COMPUTERS POSSESS DATA IN BOTH DISCREET AND WAVE FORMS.
A cellphone produces electromagnetic energy in the form of radiofrequency radiation to communicate with cell towers. This energy is used to transmit and receive signals for voice calls, texts, and data transfer.
Yes, computers primarily process digital signals, which are represented as discrete values, typically in binary form (0s and 1s). However, they can also interact with analog signals through devices like analog-to-digital converters (ADCs), which convert analog signals into digital form for processing. Ultimately, while the core processing occurs in the digital domain, computers can interface with and handle analog signals when necessary.
Data is a form of stored knowledge by computers and other forms of technology.
In wired connections, the medium that carries data in the form of light signals is typically optical fiber. Optical fiber cables use glass or plastic fibers to transmit data using pulses of light, allowing for faster and more reliable data transmission compared to traditional electrical cables.
Transmission channels are defined as paths through which electrical signals can pass through. It may be in form of a physical cable.
Electromagnetic waves in the form of radio signals travel between telephones to carry voice and data transmissions.
Data refers to information, facts, or statistics that are collected, stored, and analyzed for various purposes. Data can be in the form of text, numbers, images, videos, or any other type of information that can be processed by computers.
The physical layer is layer 1. It comprises the hardware (routers, repeaters, hubs, switches, etc.) that are used to form the physical basis of a network. They receive, process, and transmit raw electric (or optical) signals, rather than logical data packets.
The noun computer is the singular form; the plural form is computers.
An antenna works by converting electrical signals into radio waves for transmission and vice versa for reception. When an electrical current flows through the antenna, it creates electromagnetic waves that can travel through the air. These waves carry information in the form of radio signals. The antenna's design and length determine the frequency of the radio waves it can send and receive.
